lower rad hose and pull thermostat then put low psi feed through the upper rad hose assuming you put it back w/o thermostat

will purge all fluid out....

ok ok, drained about a gallon out of the petcock which was lower then rad hose yesterday. Found tester today so will check level. Oil is good so I hope level is good... parked in Chwk for 2-3 yrs so it got cold there too but not like -28 few days ago. My Jimmy wasa at -20 and it did not even gel up. I guess using a rifle my 303 would it be powerful enough??
